This setup has been great and the post above was near the start of my journey. Check out RoboTar on my website (http://www.Robo-tar.com
). We presented at the mini Maker Faire in Greenbrae, CA this month and in 2 weeks we'll show it at the Clean Tech Expo in Benecia, CA. If anyone is interested in following Robo-Tar's progress (Adafruit will come along for the ride)... please fill in a contact us form on the website and we'll let you know when we're ready for our Kickstarter project.
